# min_level_* MergeTree 表设置

> ClickHouse 在 min_level_* 自动生成分组中的 MergeTree 表设置。

export const SettingsInfoBlock = ({type, default_value, changeable_without_restart}) => {
  return <div className="not-prose" style={{
    display: "flex",
    flexWrap: "wrap",
    alignItems: "baseline",
    columnGap: "0.5rem",
    rowGap: "0.125rem",
    margin: "0.375rem 0",
    fontSize: "0.8125rem",
    lineHeight: "1.125rem"
  }}>
      <div style={{
    fontWeight: 600,
    opacity: 0.72
  }}>类型</div>
      <div style={{
    overflowWrap: "anywhere"
  }}>{type}</div>
      <div style={{
    fontWeight: 600,
    opacity: 0.72,
    marginInlineStart: "0.5rem"
  }}>默认值</div>
      <div style={{
    overflowWrap: "anywhere"
  }}>{default_value}</div>
      {changeable_without_restart && <div style={{
    fontWeight: 600,
    opacity: 0.72,
    marginInlineStart: "0.5rem"
  }}>
          无需重启即可更改
        </div>}
      {changeable_without_restart && <div style={{
    overflowWrap: "anywhere"
  }}>
          {changeable_without_restart}
        </div>}
    </div>;
};

这些设置可在 [system.merge\_tree\_settings](/docs/zh/reference/system-tables/merge_tree_settings) 中查看，并且是根据 ClickHouse 源代码自动生成的。

<div id="min_level_for_full_part_storage">
  ## min\_level\_for\_full\_part\_storage
</div>

<SettingsInfoBlock type="UInt32" default_value="0" />

<VersionHistory rows={[{"id": "row-1","items": [{"label": "25.10"},{"label": "0"},{"label": "新增设置"}]}]} />

仅在 ClickHouse Cloud 中可用。对数据分区片段使用 Full 存储类型而非 packed 所需的最小 part 级别

<div id="min_level_for_wide_part">
  ## min\_level\_for\_wide\_part
</div>

<SettingsInfoBlock type="UInt32" default_value="0" />

<VersionHistory rows={[{"id": "row-1","items": [{"label": "25.10"},{"label": "0"},{"label": "新增设置"}]}]} />

创建 `Wide` 格式而非 `Compact` 格式的数据分区片段所需的最小 part 级别。
